Poor Performance; Starting Difficulties; Gearbox - PIAGGIO Ape Workshop Manual

Troubleshooting

Poor performance

POOR PERFORMANCE - POOR COMPRESSION - GAS LEAKS
Possible Cause
Loosening of screws and nuts
Possible Cause
Timing incorrect
Head, cylinder or spark plug not fitted correctly
Current leakage of the ignition system.
Excessive incrustation on the lights of the cylinder.
Silencer blocked

Starting difficulties

Possible Cause
Clogged jets, carburettor body or cock
Air filter clogged or dirty
Inefficient spark plug
Discharged battery
Inefficient dynamotor
Rapid inefficiency of the regulator and battery

Gearbox

Possible Cause
Excessive clearance between the gears of the transmission
Insufficient oil in the differential transmission
Bearings of the gear shaft are noisy
Possible Cause
Overfilling of the differential gear oil
TROUBL - 44
LOW POWER
STARTING PROBLEMS
TRANSMISSION NOISE
OIL LOSS FROM THE DIFFERENTIAL UNIT
Operation
Relock nuts and bolts of the specific elements of the engine
(carburettor, cylinder head, silencer attachment), observing the
values of related torques.
Operation
Carry out the checks required for the Ignition Timing Con-
trol.
Correct the fitting and the locking.
Locate the leakage and act accordingly.
Descale.
Descale with iron wire bent into a hook or with compressed air
introduced into the cylinder nozzle fixed to the cylinder prior
external exhaust pipe heating.
Operation
Remove and clean in petrol;
Dry with a compressed air jet.
Replace.
Clean and adjust the electrodes or replace.
The battery is the electrical device in the system that requires
the most frequent inspections and thorough maintenance. Fre-
quently check that the fluid level fully covers the plates; if not,
restore the level by adding distilled water (never use natural
water, even if it is drinking water) and check fluid density at the
same time, as described in the "Battery" section.
If the vehicle is not used for some time (1 month or longer) the
battery needs to be recharged periodically. The battery runs
down completely in the course of three months. When the bat-
tery is being placed on the vehicle, make sure that the connec-
tions are not misplaced, keeping in mind that the black ground
cable with the silencer attached to the frame is to be connected
to the negative terminal whereas, the other cable, must be con-
nected to the terminal marked +.
Identify defects and make any revisions as stated in the section
"Disassembly and reassembly of dynamo motor".
Check that the connections to the battery have not been re-
versed.
Operation
Review and replace the worn components.
Restore the oil level or replace.
Replace.
Operation
Bring back to level.
